I've decided to try this bookmaker, I haven't seen many reviews of it.
You only need a valid mobile number in order to open an account, then I've used my verified WebMoney account and I tested this bookmaker as follows yesterday:
1) I've deposited $10 and placed it on a bet with very low odds, I tried to withdraw $10.20 - the deposit & withdrawal were processed both instantly without any trouble.
2) I've then deposited another $150 and placed it on a bet in one NBA Preseason Game, Under 221.5 between Knicks and Wizards - the bet won, and I tried to withdraw $271.50 which was processed with a 3% fee - I received only $263.36 ... They never mentioned in their fees page anything about that - they only mention the following:
Commission applied on withdrawal if total amount of bets placed is less than 15% of deposited funds or you are trying to withdraw funds more than 1 time per day.

That withdrawal was first withdrawal I made today and I did risk 100% of the deposit on odds of 1.81 (which are also terrible btw in comparison to NBA odds but let's leave all this asides and call it small potatoes).
I then decided to give it another try, and I made a $500 deposit.
I've placed it on a tennis bet with odds of 1.21 and the bet won, I then tried to withdraw and received the following SMS sent to my mobile device:

I've contacted their support, and this is the conversation between us:
Me: I tried to make a withdrawal but it wasn't processed - why?
BM: Helpdesk will be back in 3 hours.
Me after a few hours: ?
BM (Tatjana): Hello.As I can see, withdrawal declines due to limits on your WebMoney account. Please try the attempt again in some time. You can also contact WebMoney for further information about your limits. Thank you!
Me: There are no limits on my WebMoney wallet, the limit is set by you.
Me: And what is "in some time"? Please don't be vague.
BM (Tatjana): We do not have limits for your withdrawals. Please try to withdraw again later today.
Me: What is the definition of "later"? 1 hour from now? Why would it be any different later than now?
BM (Tatjana): You can contact WebMoney already now and specify question about your limits. If there are no limits, then you can try to withdraw later today. Unfortunately, I don't have specific timeframe.
Me: I have no problem sending and receiving funds with WebMoney, I am not sure why are you using such excuses.
Me: I have a user in SBRForum for over 9 years, I will have to report this to them with screenshots which were already taken, this is unacceptable, I'm sorry but I simply don't believe what you're telling me, there isn't any problem with my WebMoney account.
BM (Tatjana): Please do not worry. You will receive your money. Please just try again to withdraw later today. If this error will appear again, contact us.
That chat was 1 hour ago.
In the meantime I've tried to place bets on small odds (1.01) to see if it will change anything in the system, but nothing happened, I told myself maybe they want me to bet again on high odds - so I've placed a bet of my entire balance on Philippines NCAA Basketball game - you can see the bets here:

The bet on the basketball game if I click on it shows more details:

The game is still taking place right now as I type this message - you can see the final score here:
The game has ended 73-71 (144 pts in total), the bet was settled as a winner, I tried to withdraw the funds - and the button is not even available now!

BetMaster is blaming WebMoney for something that they control, it reminds me of 1XBet, same tactics, same unscrupulous practices.
I don't know what to do now, but I wanted to warn other forum members this website is very risky to use, I will report if anything changes.
